Improve Bulk Email Verification And Validation With Tools

December 25, 2021

Email Marketing is a very cost-effective marketing strategy. In the past time, companies used to meet customers or call them personally to let them know about their product. However, this process is time-consuming and lengthy and many customers don’t have the time to sit for a meeting or attend a phone call. That’s when email marketing came in handy. Companies now don’t have to wait for a long time to let their customers know about what they provide. They can send emails to customers to draw attention to their products and wait for them to respond. This way of connecting with the recipients gives them time to think and research on their own before responding. The process gets more accurate with email verification.

Email marketing can be very effective if it is done in the right way. There could be a lot of invalid emails after collecting emails which can reduce the delivery rate and increase bounce rate. To avoid this situation, it is necessary to adopt the right approach to verify and validate bulk emails.


  • Email marketing is an incredible strategy to attract the attention of the customers where companies can send emails to their leads and prospects to let them know about their product.
  • In order to do email marketing, a huge list of email ids of customers is collected from various sources from which many email ids are not valid.
  • It is necessary to identify the invalid email ids to reduce bounce rate and increase delivery rate.
  • To identify invalid emails, it is needed to check the syntax, domain and detect the disposable email address.
  • Emails can end up in the spam folder instead of the inbox. So, it is necessary to find these emails too.
  • There are many online tools that can help to differentiate invalid emails from valid emails.
  • VerifyBee, EmailListVerify, Bounce, ZeroBounce, NeverBounce, AeroLeads are some commonly used online tools.

Why Is Email Verification Important?

Email collection is the first step in the email marketing strategy and from the collected emails there could be many email ids that are invalid or non-existent. Some could land in the spam folder too. This type of email can decrease the delivery rate and increase the bounce rate which is a big disadvantage. That’s why it is necessary to validate and verify the emails after collecting them. This work requires a lot of time but with the advancement of technology, there are many tools that can do this work automatically.

Types Of Email Verification Tools

There are two types of email checker tools that can do this hard work very easily.

Real-Time Verification Using API

This service is used to verify the quality of email addresses in real-time. All you need to do is to integrate the API into your website or application. This will help you to eliminate the emails addresses that are not usable such as invalid, typo, not found, and many more from your database. For instance, when you sign up to create a new account and enter your email address, a verification is performed to check if you have entered a valid address or if this email matches with other emails.

Verify Emails In Bulk

This type of email verification is used mostly in email marketing where you just have to upload the list of emails you have collected and it will give you the list of valid emails as output. This is done by the following steps -

1. Email Address Syntax Check

Email addresses have a format. So it’s necessary to maintain that format and remove those email addresses that are not syntactically correct.

2. Domain Check

There could be domains that are invalid so it is important to eliminate those emails that have incorrect domains. Domain check is a process in which a domain is verified using DNS entries and if it does not match, it is marked as invalid.

3. Spam Trap Check

This checks the email addresses that have spam seeds, are blacklisted, BOTs, etc. by matching with a list that contains the spammers.

4. Role-Based Account Check

Company email contains specific role names in their email ids such as if a person belongs to sales department their mail contains “sales@”, if they are admin, the id contains “admin@”. This account check can help to find the correct emails and remove the invalid ones.

5. Disposable Email Address (DEA) Detection

There are some email addresses that are temporarily created for some purpose. These emails are disposed of after their use. So, they are of no use in email marketing.

Disposable Email Address Detection helps to find these temporary emails to eliminate them from the list

6. Final Verification

This phase helps to eliminate invalid emails by checking if the mailbox exists or not without sending an actual message to the inbox.
